LIDAR (Light Detection and Ranging or Laser Imaging, Detection and Ranging) is an active optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target.

Normally consultants (LiDAR survey) provide me with data to my specifications; already in ESRI GRID or ASCII GRID format. This way LiDAR data can be easily used with ArcGIS.
This time I only have xyz ...

I do have DEM of 1x1 meter and original LiDAR point cloud in .las, that DEM is made of. I need to extract river dikes (highest points of the dikes) to vector feature (point, polyline). Any idea for ...

I am looking to host lidar data on my own server and give clients the ability to view that data through a web browser as a 3D point cloud (file would be in .las format or equivalent), possibly with ...

In order to extract the vegetation mask in ecognition, with object base analysis, with creation of the rule sets, the buildings were also classified! Any idea how to extract building from vegetation? ...

I want to load approximately 10 large LIDAR tiles for analysis. I have tried using ArcScene but it appears there is a limit on how much data ArcScene can handle at one time. Each tile is 65-90MB in ...

What is the present procedure to load LAS files in QGIS 2.0.1?
After some searching I found a paper outlining the procedure; however, it was for 1.8.something, and related posts here are all rather ...

Are there any publicly and free (not necessarily open-source) applications that can remove duplicate points from LiDAR clouds?
I would like something on the lines of lasduplicate -unique_xyz, which ...

I followed this thread in order to clip .las data based off of a polygon shapefile. However I have over 100 .las files I need to clip based off of this polygon and merged into a single .lasd file and ...

I have vector data representing forests/trees/buildings that have been automatically extracted from LiDAR data. I am looking for specification/guidance for LiDAR derived products, or any standard for ...

I am using ArcGIS 10.1 to generate a DEM (bare earth) from LAS dataset. To accomplish this, I use 'Las Dataset to Raster' tool as described in Esri website.
I have read here and there in the web that ...

I have huge amounts of lidar data stored as tiled datasets per project. The "tiles" are separate LAS files based on our national map sheet setup (800 by 600 meter). To keep an overview of the data I ...

I am having difficulty properly visualizing aerial LIDAR data from the csc.noaa.gov source.
Taking any of the .laz files, the point cloud displays as an extremely long thin line of points. Zoomed in, ...
